牝鸡司晨 is a Chinese idiom (chengyu) meaning “a hen crowing at dawn (figurative)”. Refers to a woman usurping authority or assuming a dominant role traditionally held by men, often implying disorder or an unnatural state of affairs. Literally, “A hen crows at dawn”.
During the Shang Dynasty, King Zhou became infatuated with Daji, a beautiful woman from the state of Su. Daji was known for her cruelty; upon seeing ants perish on a heated bronze basin, she suggested to King Zhou a brutal form of torture called "Paolao," where criminals were tied to scorching hot copper pillars.
After King Wu of Zhou successfully overthrew the tyrannical Shang Dynasty, he reportedly remarked, "When a hen crows at dawn, the household is bound to decline."
This statement later became the origin of the idiom "牝鸡司晨," which metaphorically refers to women usurping authority and causing disorder, seen as an unnatural disruption of traditional order.
